🔍 Key Concepts

• 46 CFR requirements for inspection of hazardous materials on manned vessels • Difference between when cargo is loaded, before port entry, and ongoing periodic inspections • How the presence of a fixed fire-detection system affects inspection frequency

💭 Think About

• Ask yourself: Is this regulation about a one-time inspection event, a repeated interval, or both? • Consider how regulations typically treat vessels with vs. without fixed fire-detection systems—does that remove the inspection requirement or just change its timing? • Think about whether U.S. regulations usually pick one specific time or require multiple stages of safety checks for dangerous cargo.

✅ Before You Answer

• Verify whether 46 CFR mentions daily (24‑hour) inspections for manned vessels with hazardous materials on deck or in accessible spaces. • Check if the regulation explicitly ties inspections to arrival at a U.S. port or completion of stowage, or if those are just reasonable-sounding but incomplete ideas. • Confirm whether the presence of a fire-detecting system changes the need for manual inspection or only the frequency/conditions under which it must be done.
